BOLTON L. CORSON, OF PLYMOUTH MEETING, PENNSYLVANIA.

PIPE.

Application filed February 9, 1921. Serial No. 443,579.

To all whom it may mace-m Be it known that I, BOLTON L. CORSON, acitizen of the United States, residing in Plymouth Meeting,Pennsylvania, have invented certain Improvements in Pipes, of which thefollowing is a specification.

My invention relates to improvements in tobacco pipes, the principalobject of the invention being to provide means whereby the accumulationof tobacco which invariably forms in the bottom of the bowl may beloosened and entirely separated from the bowl and emptied out withoutthe necessity for employing an external cleaning implement.

The invention will be more readily understood from the attacheddrawings, in which:

Figure 1, is a vertical longitudinal. section of a pipe made inaccordance with my invention;

Fig. 2, is a vertical section of the bowl on the line 2-2, Fig. 1;

Fig. 3, is a detached perspective of the cleaning element, together withits operating handle;

Fig. 4, is a vertical section illustrating a modification of the devicewithin the scope of my invention;

Fig. 5, is a detached perspective of the cleaning element of themodification illustrated in Fig. 4;

Fig. 6, is a View in perspective of a pipe made in accordance with myinvention, illustrating, a further modification, and Fig. 7, is avertical section of the pipe illustrated in Fig. 6.

WVith reference to the drawings, the pipe may comprise the usual woodenor other bowl member 1 from which extends a perforated shank or stem 2.In the base of the bowl I have mounted, inthe present instance, acleaning element 3 shaped, as shown in Figs. 2 and 3, to conform to thecross setional contour of the interior of the bowl and having in thepresent instance depend ing downwardly therefrom through a suit ableaperture 4: in the base of the pipe a spindle 5, which stem extendsbeyond the under side of the pipe and has attached thereto in a suitablemanner a handle 6, said handle in the present instance being in the formof a cross, the arms of which extend substantially across the base ofthe bowl.

The operation of the device will be apparent. hen it is desired to cleanout the contents of the bowl, it is merely necessary to turn the handle6 to cause rotation in the base of the bowl of the cleaning element3,'the arms 8 and 3 of which element are thereby made to move over andto scrape the bottom and sides of the interior of the bowl, looseningany deposit of tobacco in the base of the bowl. The arms of the cleaningelement may, of course, vary in number, and are preferably made thin soas to lie flat against the sides of the bowl. The said arms furthermoremay extend upwardly in the bowl to any desired height, even to theextreme top of the bowl if this is found desirable, but it is preferredto extend these arms upwardly only to an extent substantially asillustrated in the draw ings, so that the upper portion of the bowl ofthe pipe, which is comparatively easy to clean and which does notordinarily accumulate the sodden tobacco masses found in the bottom ofthe bowl, may undergo the well known caking process in which a harddeposit is formed upon the walls of the bowl commonly supposed to givethe pipe a good flavor.

It will be understood that although I have shown and described the stem4 extending through the bottom of the pipe, this being the preferredform, it is possible to extend the stem through the side of the bowl, inthe manner, for example, illustrated in Fig. 4. In this modification,the stem 7 is attached to the top of one of the upwardly extending armsof the cleaning element 8 which is semicircular in form to conform tothe also semicircular contour of the bottom of the bowl. The stem 7 hasa suitable arm or knob 9 at the outer end by means of which the stem isoscillated with the result that the element 8 is given an oscillatorymovement around the upper end of the arms thereof as a pivot. Othermodifications are possible with no departure from the essential featuresof the invention.

I do not desire to limit myself to any particular form of knob or handlefor actuating the cleaning element, since this can be of any formdesired and may for example, as shown in Fig. (3, be in the form of anextension 10 of the bowl of the pipe whereby except for the dividingline between the knob and the bowl proper, there will be no indicationthat a mechanical device of the nature described is mounted in the pipe.

I claim:

A pipe comprising a bowl, a stem extending from the bowl, a cleaningelement movably mounted in the bowl, 21 shaft secured to said elementand extending through an aperture in the bottom of the bowl, and anoperating element for the cleaner secured to said shaft on the underside of 10 the bowl and shaped to appear as a continuation 0f thelatter.

BOLTON L. CORSON.
